Hanjun Guo 020295b4cb ACPI / processor: Make it possible to get CPU hardware ID via GICC ... Introduce a new function map_gicc_mpidr() to allow MPIDRs to be obtained from the GICC Structure introduced by ACPI 5.1, since MPIDR for ARM64 is 64-bit, so typedef u64 for phys_cpuid_t. The ARM architecture defines the MPIDR register as the CPU hardware identifier. This patch adds the code infrastructure to retrieve the MPIDR values from the ARM ACPI GICC structure in order to look-up the kernel CPU hardware ids required by the ACPI core code to identify CPUs.
